None so far, I'm a little offended they haven't asked me yet .
I like to wind up the cranky types by making them say sweet things though. Yes I realise they have no idea what they're really saying, but having Mr Cranky come over shouting "sweetheart" or "I love you" is a petty way of me dealing with their rudeness
I have Flurry say "Yo Marshmallow", Diana say "Well well well", and Benjamin say "Hey big daddy" as greetings. I usually go with the classic "in my bed" for catchphrases.
One of mine ends every sentence with "Butts!", another starts his chat with "Gurrrl!", another says "Meka-Hi!" (from the Captain-N TV Show) and another says "Twerk it".
I made Baabara say "Hey gurl haay," and Bangle says "Gurrl" for their greetings. Also, a couple villagers are using "btch ****" at the end of their phrase. "Yo, it's you again, btch ****!" Haha! I'm sure there are some people that would hate coming to my town for this exact reason, but I find it hilarious.
Greetings:
Chu (should really be a catchphrase)
Gr?? dich
Flamio Hotmen (come on, A:TLA fans...)
Animaux Sauvage
SQUIRREL (Nibbles XD)
Greetings (yes. I know... But I like Coco to stay cute and cuddly d'awwwww)
Catchphrases:
Sea lily (so cute when Coco says it ;w; )
Old Sport (Papi says this. I think he has nice furniture but a clashing personality.)
Darlin' (Violet)
Tasty (Lobo says this. It's funny when I wear the bunny hood)
Ham n' egg (Curly says this. Looks like I miss certain foods)
I like to change my animals' catchphrases to Pokemon that reflect their species. For example, Chow's catchphrase is "snorlax", Willow's is "mareep", and Chief's is "growlithe", just to name a few. :3
For greetings, Ruby has "Hoppy to see you" and Pierce says "WHADDUP HOMIES!"
As for catch phrases, I think I have Pierce with "broseph", Jay with "broski", Gala with "oinkers", and Hazel with "*snort*".
I kind of want more of them to ask me to change their greetings, so I can squeeze in more silly puns.
